AERIAL NAVIGATING DEVICE.

Specification of Letters Patent. Patented July 25, 1911.

Application filed November 13, 1909. Serial No. 527,765.

, the city and county of Philadelphia, State into water.

of Pennsylvania, have invented a new and useful Aerial Navigating Device, of which the following is a specification.

purposes.

My invention consists of anaerialnavigatin device of the order of a helicopter, in WhlCll I employ blades, with means to adjust them in vertical, horizontal and inter mediate positions, so'that the device may be raised and propelled ahead or in reverse directions at the will of the aviator.

' It consists further in providin the body ofthe device with win at the si e thereof, the same being adapte to be angularly lowered to lessen the resistance to the air in rising, and when-at a desired height to be further operative raised horizontally for i It consists furtherof the application to the body of the device, of a receptacle for air or gas to increase the buoyancy of the device.

during navigation andrprovlde a pontoon or float to sustain the device should it fall It consists further of novel steering mechanism.

It consists further of details of construction as will be'hereinafter set forth.

For the purpose of explaining the invention, the accompanying drawings illustrate a satisfactory reduction of the sametopractice, but the important instrumentalities thereof may be be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization 1 shown and described.

Figure 1 represents a side elevation, partly broken away, of an aerial navigating 7 device embodying my invention. Fi

2 represents arear end elevation thereof.

3 represents a top 'or plan view thereof.

Fig. 4 represents a section of a portion on line M, Fig. 1. Fig. 5 represents aside. elevation of a detached portion. Fig. 6 represents alsection thereo on line y-g, Fig. 7- represents a section on line z--z.

Similar letters of reference indicate. cor responding parts in the figures.

the body 0 an aerial car or navi ating device, the same being com osed o the sides or bulwarks B, the floor and the keels D, the latter forming a stand or support for the device when on the ound.

Hinged to the sife s B are the wings E, which are adapted to be placed in horizontal or downwardly inclined positions by means wings, passed over. the pulleys G and extended on the .floor C, said pulleys being mounted on the frame J, which rises from the sides B, it being evident that when said windlass is operated, the wings may be raised or lowered, so that when lowered,

ascent of the device, and when at a desired height they may be placed in horizontal position for further 0 eration of the device.

K designates bla es, which are carried on the 'rotatable shafts L, the latter being connected by the gearing M with the driving shaft N, which is operated from the engine P in any suitable manner, said shafts L being adapted: to turn on the shaft N, so as to positions, whereby when power is communicatedto the shafts L, the blades K are rotated, and thus thedevice ma be raised or propelled ahead, according tot e angular positions that said shafts L may occu y, they being shownvertical in Figs. 1 an 2 and horizontal in Fig. 3.

The shafts L are passed freely through the sleeves Q, with which are connected the heads R, the necks of which freely occupy the slots .S-of the segmental guides T,'which are firmly connected with the cross piece T above the floor of the body A andthe top of the frameJ, it being noticed that the heads R are adapted to slide on said slots S in the operation of adjusting the angular position of she shafts L, and consequently of the bla es.

they lessen the resistance to the air in' the occupy vertical, horizontal or intermediate Referrin' to the drawings :A designates l of the cords F which are secured to the said ed to the Windlass H, which latter is mount- To the sleevesQ, there are pivotally at.-

motion may be tached the swinging arms U, the lower portions having therein the slots V, through which passes the shaft W, the latter having its bearing in standards rising from the floor of the body A, the walls of said slots V being adapted to slide on said shaft W in the rising and falling motions of said arms U. A portion of said walls of each slot V is toothed, forming the rack X, with which meshes a pinion Y on said shaft W, so that by the operation of the pinions, motions are imparted to the racks, and consequently to the arms U, whereby the shafts L may be in their angularly-adraised and lowered justable positions, so as to place the blades in vertical, horizontal, or intermediate position while rotary motions are being imparted to said shafts L from the engine employed.

In order to operate the pinions I employ the idler Z, which meshes with ne of said pinions and with apinion A n the shaft of the hand wheel B, said idler and hand wheel being mounted said standards rising from the floor of the body, and said hand wheel being inconvenient reach of the aviator, so that when the wheel is rotated, communicated quickly to the pinion Y geared therewith and then by the shaft W to the opposite pinion, whereby the arms U may be raised and lowered, as hereinbefore referred to, and in an easy and rapid manner.

As one of the walls of each slot V is untoothed, in order to prevent the pinion Y from frictional contact therewith, the shaft of said pinion has secured thereto the collar C, which is located aside of said pinion and is adapted to ride freely on the untoothed wall of a slot D, formed on a separate plate or'track E, which is secured to the side of the adjacent portion of the arm U and somewhat set-out therefrom, as best seen in Figs. 6 and 7.

F designates the rudders of the device, the same being freely fitted in openings in the keels D, and pivoted to the walls thereof, they being coupled by the cross bar G,-

so as to work in unison, said bar having connected with it the cord H, which is passed around the Windlass or drum J, the latter having a hand wheel K, whereby when said wheel is operated the bar G receives motion to the right or left and the same is communicated to the rudders, so as to conveniently and effectively steer the device.

Mounted on the sides of the keels D, are closed cylinders L which form receptacles for air or gas, serving to impart buoyancy to the device during navigation, and provide a pontoon, float or raft to float the device should it drop into "water.

The engine -P may be duplicated, the two engines to be coupled to the shaft N, so that either engine may be run independently of the other, and one engine run slow and the other engine run fast in order to preserve the equilibrium of the device. Again, should one engine be disabled, the other may be used, and so the device may continue its navigation or land as desired, and this with safety.

In landing the device, the blade shafts L are placed in vertical position and the speed of the blades is decreased, and the device may be backed when so desired. I

The sleeves Q, are sustained by the arms M, which rise from the bearings of said shafts L and are connected with said sleeves and bearings,.and so retain said sleeves in proper position on said shafts.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v 1. In an aerial navigating device, a propeller blade, means for rotating the shaft thereof, a tubular member in which said shaft is mounted, a driving shaft on which the propeller shaft is mounted to turn from a vertical to a horizontal position, a swinging arm pivotally attached to said tubular member and having at its lower end a slot with a ,rack, a pinion meshing with said' rack within said slot, and means for operating said pinion to raise and lower said shaft in its angularly adjustable position. v
